In Traditional Gaelic Bagpiping, 1745 - 1945 (McGill-Queen's University Press, 1998, ISBN 0-7735-1541-0), author John G. Gibson addresses the question of the continuity of tradition in bagpiping and whether it is an example of the "invention of tradition" or whether there is a continuous development capable of being traced back to pre-Culloden days and where that continuity can be found.
